Wave Interactions

Front

What is Reflection in wave interactions?

Back

Reflection is the bouncing back of a wave when it hits a surface that does not absorb the wave's energy.

Front

What is Refraction in wave interactions?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is Diffraction in wave interactions?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is Radiation in the context of wave interactions?

Back

Radiation refers to the emission of energy as electromagnetic waves or as moving subatomic particles.

Front

Which of the following is NOT a cause of a wave changing direction?

Back

Radiation is NOT a cause of a wave changing direction.

Front

True or False: Refraction causes waves to bounce back off of an object.

Back

False. Refraction involves bending, not bouncing.

Front

What happens to light when it reflects off a surface?

Back

Light bounces back at the same angle it hit the surface.

Front

Can sound waves also undergo reflection?

Back

Yes, sound waves can reflect off surfaces, similar to light waves.

Front

What is the principle of superposition in wave interactions?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger wave, while destructive interference occurs when waves combine to make a smaller wave or cancel each other out.
